Motor Learning and Physiological Adaptation
Conditions
Brief summary
The aim of the study presented here is to assess the effects of exoskeleton training on performance in a real hypergravity situation. In particular, it will analyze fine motor control, autonomic nervous system regulation and metabolic responses. To this end, the study will compare two groups during a pointing exercise in a centrifuge (hypergravity). One group will have been trained to do this exercise using an exoskeleton, while the other will have been familiarized with the task without the exoskeleton. It will assess whether the exoskeleton can be an effective and accessible training tool for astronauts.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Task performance (movement accuracy) | From familiarisation sessions (Day 1 to Day 4) to testing day at Day 5. | Task performance (movement accuracy) is defined as the difference between the position touched on the screen and the position of the displayed target. The participants will be required to perform an aiming movement task using their right arm, directed toward a target.The participants will need to point to the center of the displayed target. |
